Well guys I'm still recovering today from flyday as it was a busy one.

Yesterday when I came home in the late afternoon. My wife just knew of my deluged day. She asked as I was carrying my MX in by the tail with the nose down. Honey your home early. I replied yeah, I broke a prop and bent the landing gear.
She Intenly looked the MX over seeing the cracked and chipped cowl and the mangled landing gear. I could tell she was remembering how shiny an new she looked only not that long ago.
She then asked is that the only plane you took to the field, To which I replied yes.
Now I could tell things were building as she asked is that the only one you have flyable.
I sheepishly answered YES as I walked away. Only to hear her rebuttal Easy come easy go Hun.
Needless to say I left it alone and went to the walmart Deli for some Tao chicken.
That put a smile on momma's face

My wife usually just says, "Did you crash anything?" It is almost like she thinks I crash something every time I go out. I think I might have a broken plane 10% or less of my trips to the field. Of course, when I have multiple breaks on one trip, that only counts as one.

I took out two SLA, 12V field batteries from my starter box and put in a 8000mAh, 4S lipo.

A lot of times we have problems getting starters to turn over our engines. Often, the starter is blamed. I believe it is frequently the battery. The field batteries just won't deliver the current to let that starter motor turn over the engine. This is good for the starter companies selling bigger starters, belt drive, gear reduction, etc. The gear reduction systems help because the take the wimpy battery current and employ a mechanical advantage to get it to work.

I converted a starter to lipo for one of the club members a while back and he is very happy now. I just converted another one this week. I removed all the nimh cells and put in a 4S, 1800 mAh. Both of those applications were using Sullivan battery packs that bolt on to the starter.

I use a charger with a cord with banana plugs. My field battery box has two sets of banana jacks so I can plug in a charger and a pump. I had the two field batteries setup to provide two 12V outputs and one 24V output.

I am charging my new pack. I will see how it does in the next few weeks. The lipo cost about what three regular field batteries would cost. It is a 30C pack so it should be able to supply about 240A. That should start something.

I switched to 3200 4 cell lipo to turn the starter, even though it is rated for 12 volts.

put in a mini motocycle battery in the box as well for back up and to pump the fuel.

its nice to use a separate 4 cell lipo for starter becaus ethe box can be left at the car or ground station.

all I need now is the glow plug starter, which gets charged just before take off

and the prop. spinner at 4 cells which gets it spinning, well better than before

4 cells lipo was most likley the problem to severe "jump" off of the spinner when valves or whatever were gummed up from over storage

I still need to pull back the motor, or turn back the motor to the point of starting easy, at full compression even 4 cells does not turn over a 125 or 91 4 stroke

goes to show the saitos have high compression

Well it's warm this morning and a bit windy but I'm afraid work has once again kidnapped me. They caught me yesterday for a carpet job. And now a sewer back up job. O what a man won't do for a dollar.

Calling 62 here today, they are calling for the wind to pick up though, but only to about 12 mph. Just might take the afternoon off and go fly!! Batteries are all charged up!! Rode the HAWG into work today!! Nice ride in. A bit chilly, but heated gloves do wonders!!
